How to create high-resolution iphone launch image?

Question

As per the Apple iPhone Human Interface Guidelines I have created a Default.png image which is displayed while waiting for the application to load.

I created the image using the xcode organizer 'capture screenshot' feature.

I am now preparing my application for the iphone 4 high resolution screen and am wondering how to create the high resolution version of Default.png.

Is there a way to generate it from a screen shot like the standard Default.png image?

Answer 1

The easiest way I found is to use the special "Copy Screen" menu option in Simulator.

While the Simulator is running, hold the control key. The Edit menu will change from "Copy" to "Copy Screen". You now do a Command-V in Preview or Photoshop since the screen was saved to your clipboard buffer. Then save out the file as png.

High resolution Launch Images just need the @2x designation. You can capture them as a screen shot when running on iPhone 4, device or simulator.
